Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

Pure mathematics is in its way, the poetry of logical ideas.

You cannot escape the responsibility of tomorrow by evading it today

Fall down seven times, stand up eight.

"I" not them. Be the best version of you.

Never underestimate the importance of small steps. small steps = big changes. 

Just stick with it, what seems hard now will one day be your warm up.

I have not failed, I've just found 10,000 ways that won't work.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

Skills are built not born.

Procrastination is the thief of time and the enemy of success.

Knowledge is of no value unless you put it into practice.

Procrastination makes easy things hard and hard things harder.

Run in the morning before your body figures out what you're doing

The greatest enemy to human potential is your comfort zone
